Rain-X as an LSP?

So how did the rain-x hold up in that test Twitch?



By the way, that rain-x that they spray at the carwash on the whole car is not the same stuff you put on your windshield. It's just rain-x branded.
 
Why use normal Rain-x when they made a liquid wax especially for this purpose? I have used it and was pleased with it. It lasted on a car that sat unmoved for 2 months, through a blizzard, sun, dirt and multiple heavy rain showers and never lost protection...

Maybe he means the Icons are more prone to skip with anything applied to the windshield, compared to more common wipers, haha...
 
Using Rain-X on your paint is the equivalent of wiping the paint with isopropyl alcohol while smearing it with silicone.



This should strip any oils, waxes, etc that were in place. Further it will make it nearly impossible (without a good deep polishing) to reinstall any LSP. However it should shed rain nicely for a few weeks.



I personally believe this to be near insanity. However if anyone is convinced that this is a valid concept, I suggest bypassing the Rain-X and using Aquapel. At least it will last longer.



Just so that it is clear, I strongly advise against any of this foolishness.
 
Agree. I don't think I would want to put acidified alcohol on my paint. No wonder it sqeeks (per above post) if you apply it. :think:

From my knowledge RainX for the most part is isopropyl alcohol (as mention above), and for the most part "deep cleans" the glass. I am sure they may have more to their product but this is from what I have read or heard from word of mount.



I have a friend that used RainX and now just wipes hie widows with isopropyl alcohol and says it works the same, I have not seen the car in the rain, as he lives 100 miles away and his car has been gargae kept for the last year (doing an engine swap). I figure I may try his method, but do half and half, I will report back wit some results down the road.
 
The IPA acts as a cleaning agent for the glass and a carrier for silicone. Once the silicone is smeared onto the glass it is a huge PITA to get it off again. Which is generally necessary when you start getting smearing, streaking, wiper leaps, and so on. When she applies the IPA (also hygroscopic) she is essentially cleaning the surface and allowing the remaining silicone to function.



IPA leaves some hydrocarbon residue. My experience at work where we use 99.999% IPA shows obvious measurable residue. When I need a zero residue cleaner for glass I do not use IPA without substantial wipedown.
 
I ever tried other IPA base water repellent products





my personal observations



good Beading

bad Slick

bad Gloss

good Durable
